MCQ
$ADH$ controls water permeability of
- ACollecting tube
- ✓Distal convolulated tubule and collecting duct
- CProximal convolulated tubule
- DBowman’s capsule
✓
Answer
Correct option: B.
Distal convolulated tubule and collecting duct
b
(b) $ADH$ or vasopressine is effective in reabsorption of water by changing permeability of terminal part of $DCT$ $(distal\,\, convoluted \,\,tubules)$ and collecting ducts.

Assertion: After formation of hormone-receptor complex, biochemical changes in the target tissue occurs.
Reason: Hormones produce their effects upon target tissues only by binding to specific proteins called hormone receptors located in the target tissues.

Which of the following statements are correct for regulation of cardiac activity ?
(i) A special neural centre in the medulla oblongata can moderate the cardiac function through autonomic nervous system.
(ii) Neural signals through the sympathetic nerves can increase the rate of heart beat, the strength of ventricular contraction and thereby the cardiac output.
(iii) Parasympathetic neural signals decrease the rate of heart beat, speed of conduction of action potential and thereby the cardiac output.
(iv) Adrenal medullary hormones can also increase the cardiac output.
(v) Adrenalin or epinephrine increase heart beat.
(vi) Acetylcholine decrease heart beat.
